Document Summary

Read section 11. 2, 11. 3 up to and including p. 411 ignore p. 412 3 (6th ed) or 429 30 (5th ed) Thursday, oct 16, 8am thursday, oct 23, 8am. A covalent bond is formed when atomic orbitals of different atoms overlap. Each atom contributes a single valence e with opposite spin. For groups 1 + 17, the theory works ok. Also in methane, ch4, all c h bonds are identical. Beware: this different explanation (hybridization) has no experimental proof that hybrids actually exist. quantum solution. Atomic orbitals are mixed together (hybridized) to form molecular hybrids. Mix four ao (one s + three p) four sp3 hybrids. See table 11. 1 for the shape of the four sp3 hybrids. Four large lobes (the smaller back lobes are usually obscured when all the 4 sp3 hybrids are sketched) four sp3 tetrahedral geometry (109. 5 ) Note that the sp3 energy levels are higher than the s level but lower than the p energies.
